About Promptfoo
Promptfoo tracks every frontier model within days, and now ships itself as agent skills
Promptfoo is an LLM evaluation and red-teaming harness, releasing at a pace set by the model market rather than by its own roadmap. The provider list absorbs new frontier models almost as they launch — Claude Opus 5, Claude Sonnet 5, Claude Fable and Mythos, GPT-5.6 on Bedrock and at GA, Grok 4.5, Kimi K3, plus Bedrock coverage for GLM, MiniMax, Nemotron, Gemma and Palmyra. Around that, the work is harness ergonomics: per-test repeat, websocket URL templating and subprotocol surfacing, YAML source locations in prompt reference errors, and a steady stream of assertion-scoring corrections.
